he device may be made in various sizes and in various ways the details of construction may be modified and still be u ithin the scope of my invention. I claim as my invention:

1. The combination, with a service pipe, of a shell tapped therein and having ports a gas cock fitting within said said shell, said cock having a tapered outer end, a pin mounted in said cock and projecting'laterally therefrom, a cap having an opening through which the tapered outer end of said cock projects, a coupling having a socket to receive said tapered outer end and a recess for said pin, said coupling also having laterally projecting lugs, and yielding means interposed between said lugs and said cap and engaged by said lugs when said coupling is rotated for drawing said coupling and cock together.

2. The combination, with a service pipe, of a shell tapped therein, a gas cock seated in said shell and having a passage to register with ports in said shell, a cap for the outer end of said service pipe and shell, a

coupling having a tapered socket to receive the correspondingly shaped end of said cock, said cock and coupling having means for interlocking to rotate said cock when said coupling is revolved, a Washer having cam surfaces. interposed between the inner end of said coupling and said cap, and said coupling having means for engaging with said cam surfaces for drawing said coupling and cock together when rotated to expose said ports.

3. The combination, with a service pipe, of a shell tapped therein and provided with a flanged outer end and a recess encircled by said flange, a gas cook fitting within said shell and having a passage communicating with ports therein leading to said service pipe, a cap covering the outer end of said shell and having an opening therein through which said cock projects, a coupling having a socket to enter the opening in said cap and receive the end of said cock, said coupling and cock having means for interlocking with one another, a washer interposed between said cap and shell within said recess and provided with cam surfaces, means for preventing rotation of said washer, said coupling having means for engaging said cam surfaces for drawing it and said cock snugly together when said coupling is revolved.

In witness whereof, I have hereunto set my hand this 8th day of February 1916. FRANK W. OLDS.
